THERE ARE A FEW MISTAKES here and there in the factory ones. The bolt torque for LA rocker shafts was too much for a few years, so use your brain. Use Google. Bolt torque charts for U.S. grade 5 (3 point) hex cap screws........
Another mistake was in the wiring diagrams for a few years around 68--70 or thereabouts. "Magically" the yellow start wire and green/red horn wire got interchanged at the bulkhead connector
